FAN6747 is a highly integrated green-mode PWM controller with features such as high-voltage startup, AC-line brownout protection, constant output power limit, built-in 8ms soft-start function, etc. It is suitable for general-purpose switch-mode power supplies and flyback power converters, such as power adapters, printers, scanners, motor drivers, etc.
The FAN6747 is a highly integrated PWM controller designed for flyback power converters, specifically those with peak-current output. It incorporates a proprietary green-mode function that modulates off-time to decrease switching frequency under light loads, enabling the power supply to meet international power conservation requirements. The device is especially suited for applications such as power adapters, SMPS for printers and scanners, and motor drivers.
